Flu Vaccine

For the 2018-19 season, trivalent influenza vaccines licensed in the U.S. will contain hemagglutinin (HA) derived from an A/Michigan/45/2015 (H1N1) pdm09-like virus, an A/Singapore/INFIMH-16-2016 (H3N2)-like virus, and a B/Colorado/06/20017-like virus (B/Victoria/2/87 lineage). Quadrivalent influenza vaccines will contain these antigens along with a B/Phuket/3073/2013-like virus (B/Yamagata/16/88 lineage). Live Attenuated Influenza Vaccine (LAIV) will have the same HA as quadrivalent influenza vaccines except for the H1N1 component, which is A/Slovenia/2903/2015 post-pandemic strain.

Recommendations from the ACIP

Everyone 6 months of age and older should be vaccinated with any licensed, age-appropriate influenza vaccine (IIV, RIV, or LAIV), as indicated. No preference is given for any one vaccine over another. 

The Morbidity and Mortality Weekly Report published on August 24, 2018 provides guidance from the Advisory Committee on Immunization Practices (ACIP) for using this year's flu vaccine products. See this PDF for a for a listing of influenza vaccine products available for the 2018-19 season. Vaccines for Children providers can access the 2018-2019 State Supplied Childhood Flu Vaccines At-A Glance chart for VFC specific choices. 

Updates for 2018-19 flu vaccine

In its February meeting, the ACIP once again recommended LAIV (the nasal spray vaccine known as FluMist) for healthy, non-pregnant people 2 through 49 years old during the 2018-19 season.  This recommendation was made after ACIP reviewed effectiveness data presented by the manufacturers of FluMist.
